LUCAS MAVIE CAMPI, OF HAVANA, CUBA.

CALCIIVIETER.

SPECIFICATION forming part of Letters Patent No. 299,461, dated May 27, 1884.

v Applioatiouled December 10, 1883. (No model.)

To all whom it 'ma/ y con-cern:

Be it known that I, LUoAs- M. CAMPI, of Havana, Cuba, have invented a new and Improved Calcimeter for Treating Cane` Juices in the Manufacture of Sugar, of which the following is a full, clear, and exact description.

Hitherto in clarifying cane-juice with lime preparatory to evaporating the juice it has always been a matter of guess-work or mere good Io judgment as to the right quantity of lime to use, and for this reason the clarifying process as now practiced is entrusted only to a person of long experience; but he, notwithstanding his skill, is liable to err, since it is impossible to distinguish many of the impurities contained in the juice by inspecting the juice in quantity or a specimen of the mass of j uice being treated.

My-invention relates to means whereby any person, skilled ,or unskilled, may clarify or defecate cane-j uice with lime, always using the exact quantity of lime necessary to produce the best results.

Reference is to be had to the accompanying drawings, forming apart of this speciiication, in which similar letters of reference indicate corresponding parts in all the gures.

Figure 1 is a side elevation of a graduator. Fig. f2 is a plan view of my calcimeter. Fig. 3 is a side elevation of the same; and Fig. 4 is a transverse sectional elevation of the calci- Ineter, taken on the line x x of Fig. 2.

The graduator A is a vessel made, preferably, of transparent glass, and graduated at a from one hundred up to twentyeeight hundred millimeters.

B is the lime-measure o r calcimeter. This may be made of metal, wood, or other suitable material. It is formed with the recess or f f,'which run in the grooves g g, made in the sides or edges of the measure, and the said pusher C is provided with the thumb-screw C', passing vertically through the central projection, e, of the pusher, and adapted to be brought to bear on the upper surface of the groove b of the calcimeter B, for securing the pusher at any desired point along the measure.

Having thus fully'described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture, a calcimeter consisting of a bar having a longitudinal lime-receptacle, b, open at one end and graduated along one edge, as at d, and a slide, C, having a tongue, e, integral therewith, and adjustably held in said lime-receptacle, as set forth.

2. rlhe measure B, formed with groove b and side grooves, y g, in combination with the slide C, having central projection, e, and lips f f, that run in the grooves g g, and provided with the screw C', for holding the slide at any desired position, substantially as described.
